Eric,

You didn't mention what operating system you are 
using. If it is OS X then check the following (in 
the message box):

    go stack url "http://home.infostations.net/jhurley/DisplayProblemsOSX.rev"

Mark Waddingham says that this screen refresh 
issue will be address in the next upgrade. In the 
meantime you might insert "unlock screen" or 
"wait 0 millisec"
